Cheap price Digital Chlorine And Ph Tester - CH200 Portable chlorophyll analyzer – Chunye

Principle of measurement

Portable chlorophyll analyzer is composed of portable host and portable chlorophyll sensor.Chlorophyll sensor is using leaf pigment absorption peaks in spectra and emission peak of the properties, in the spectrum of chlorophyll absorption peak emission monochromatic light exposure to water, the chlorophyll in the water absorption of light energy and release another emission peak wavelength of monochromatic light, chlorophyll, the emission intensity is proportional to the content of chlorophyll in water.

Main Features

Portable host IP66 protection level

Ergonomic curve design, with rubber gasket, suitable for hand handling, easy to grasp in wet environment

Factory calibration, one year without calibration, can be calibrated on the spot;

Digital sensor, easy to use, fast, and portable host plug and play.

With USB interface, you can charge the built-in battery and export data through USB interface

Application

It is widely used for on-the-spot and portable monitoring of chlorophyll in aquiculture, surface water, scientific research university and other industries and fields.

5.Manual and automatic temperature compensation
6.Three relay control switches
7.4-20mA & RS485,Multiple output modes
8.Multi parameter display simultaneously shows – pH/ ORP, Temp, current,etc.
9.Password protection to prevent misoperation by non- staff.
10.The matching installation accessories make the installation of the controller in complex working conditions more stable and reliable.
11.High & low alarm and hysteresis control. Various alarm outputs. In addition to the standard two-way normally open contact design, the option of normally closed contacts is also added to make the dosing control more targeted.
12.The 6-terminal waterproof sealing joint effectively prevents water vapor from entering, and isolates the input, output and power supply, and the stability is greatly improved. High resilience silicone keys, easy to use, can use combination keys, easier to operate.
13.The outer shell is coated with protective metal paint, and safety capacitors are added to the power board, which improves the strong magnetic anti-interference ability of industrial field equipment. The shell is made of PPS material for more corrosion resistance. The sealed and waterproof back cover can effectively prevent water vapor from entering, dustproof, waterproof, and corrosion-proof, which greatly improves the protection capability of the whole machine.

Electrical connections

Electrical connection The connection between the instrument and the sensor: the power supply, output signal, relay alarm contact and the connection between the sensor and the instrument are all inside the instrument. The length of the lead wire for the fixed electrode is usually 5-10 meters, and the corresponding label or color on the sensor Insert the wire into the corresponding terminal inside the instrument and tighten it.
